Description

Technical Field

[0001] This application relates to concrete pouring technology, and more particularly to a concrete pouring apparatus. Background Technology

[0002] When concrete is poured and falls directly from a height, the denser aggregates separate from the less dense cement paste under the influence of gravity, a phenomenon known as concrete segregation. To prevent segregation, a tremie pipe is used to restrain the concrete and control its falling speed, thereby maintaining the uniformity of the concrete.

[0003] The existing concrete pouring tremie pipe has a hook fixed at the upper end and a hanging ring fixed at the lower end. The lower tremie pipe is hung in the hanging ring at the lower end of the upper tremie pipe through the hook at its upper end, so that the two adjacent tremie pipes are connected end to end.

[0004] During the pouring process, the concrete surface will rise as the pouring progresses. The existing concrete pouring tremie pipes cannot be moved and retracted according to the rise of the concrete surface. It is necessary to manually remove individual tremie pipes for adjustment, making it difficult to adjust the reasonable drop of the concrete in a timely manner. Utility Model Content

[0005] This application provides a concrete pouring device to solve the problems of existing concrete pouring devices that make it difficult to move and retract the tremie pipe during the pouring process and cannot adjust the drop according to the rise of the concrete surface.

[0006] This application provides a concrete pouring device, including a conical trough first, the upper end of which is connected and fixed to the bottom of a hopper. Below the trough first, there are multiple trough second that can be nested with it. Hanging rings are fixed on both sides of the upper end of the trough second, and positioning rings are fixed on both sides of the upper end of the trough first. A reel rotated by a motor is installed at the bottom of the hopper. Two independent pull ropes are wound on the reel. The two pull ropes pass through a guide ring and then pass through the positioning ring and the hanging ring from top to bottom on both sides. The lower end of the hanging ring is provided with a clamp that can hold and fix the pull ropes.

[0007] Optionally, the hopper is supported on the ground by three columns fixed to its bottom edge, and the columns are telescopic and can be fixed.

[0008] Optionally, the inner wall of the hopper is fixed with a spiral plate for decelerating and guiding the material.

[0009] Optionally, the lower end of the hopper is a slanted cone structure, and the feed inlet at the upper end of the spool is connected to the slanted cone and located below the material drop end of the spiral plate.

[0010] Optionally, an electric heating element is attached and fixed to the bottom of the spiral plate.

[0011] The concrete pouring device provided in this application has a hopper fixed above the pouring opening, and a second tremie pipe fixed on a rope and arranged downwards, extending into the formwork from the pouring opening. As the concrete surface rises during the pouring process, the pull rope can be tightened by rotating a reel controlled by a motor, moving the second tremie pipe upwards and retracting it, thus facilitating the control of the concrete detached from the second tremie pipe and keeping it within a reasonable drop range.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0016] like Figures 1-6As shown, one embodiment of this application provides a concrete pouring device, including a conical tremie pipe 2. The upper end of the tremie pipe 2 is connected and fixed to the bottom of the hopper 1. A plurality of tremie pipes 3 that can be nested with the tremie pipe 2 are provided below the tremie pipe 2. Hanging rings 4 are fixed on both sides of the upper end of the tremie pipe 3. Positioning rings 5 ​​are fixed on both sides of the upper end of the tremie pipe 2. A reel 6 that is rotated by a motor 9 is installed at the bottom of the hopper 1. Two independent pull ropes 8 are wound on the reel 6. The two pull ropes 8 pass through the guide ring 7 and then pass through the positioning rings 5 ​​and hanging rings 4 from top to bottom on both sides respectively. The lower end of the hanging ring 4 is provided with a clamp 12 that can clamp and fix with the pull ropes 8.

[0017] In use, hopper 1 is fixed above the pouring opening. Pipe 1 2 is inserted into the pouring opening, and pipe 2 3 extends downwards along the pouring opening. The number of pipes 2 3 can be adjusted according to the pouring depth. After the pull rope 8 is released by the pulley 6 rotated by motor 9, the pipes 2 3 are clamped and fixed in place by the clamps 12 on both sides, allowing multiple pipes 2 3 to extend downwards along the pouring opening and guide the concrete downwards. After the mixed concrete is poured into hopper 1, it flows downwards through pipes 1 2 and pipe 2 3 sequentially into the bottom of the formwork. Simultaneously with pouring, as the concrete surface inside the formwork rises, the pull rope 8 is rotated by motor 9 to gradually move and retract pipe 2 3, maintaining the height difference between the bottom of pipe 2 3 and the concrete surface within a reasonable range.

[0018] In this embodiment, after the hopper 1 is fixed above the pouring opening, the second duct 3 is fixed on the pull rope 8 and arranged downwards, extending into the formwork from the pouring opening. As the concrete surface rises during the pouring process, the pull rope 8 can be tightened by controlling the rotation of the pull wheel 6 via the motor 9, moving the second duct 3 upwards and retracting it, making it easier to control the concrete detached from the second duct 3 and keep it within a reasonable drop range.

[0019] In one possible implementation, the hopper 1 is supported on the ground by three columns 10 fixed to its bottom edge, the columns 10 being telescopic and capable of being fixed.

[0020] The hopper 1 is supported by the ground through three columns 10, and its height position can be controlled by the telescopic structure of the three columns 10, so that it can be flexibly erected above the pouring opening at different heights.

[0021] In one possible implementation, the inner wall of the hopper 1 is fixed with a spiral plate 11 for decelerating and guiding the material.

[0022] Spiral plate 11 can effectively slow down the falling speed of concrete, further preventing segregation during the discharge process of concrete pouring.

[0023] In one possible implementation, the lower end of the hopper 1 is a slanted cone structure, and the feed inlet at the upper end of the string cylinder 2 is connected to the slanted cone and located below the material drop end of the spiral plate 11.

[0024] The oblique cone not only allows the position of the tremie cylinder 2 to be closer to the edge, making it easier to set up the hopper 1 when pouring into the pouring port at the edge, but also makes the feed port of the tremie cylinder 2 better connected to the material drop end of the spiral plate 11, making the feeding of the tremie cylinder 2 smoother.

[0025] In one possible implementation, an electric heating element is attached and fixed to the bottom of the spiral plate 11.

[0026] When the construction temperature is low, the concrete can be kept warm by the electric heating element at the bottom of the spiral plate 11 to maintain a suitable temperature when the concrete is poured into the formwork and avoid frost damage.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
